BEST MODE FOR CARRYING OUT THE INVENTION

On the occasion of the development for dysuria treatment of oral solid medicaments comprising as an active ingredient KMD-3213 which is extremely useful for dysuria treatment, the present inventors conducted extensive investigation of preferable crystal forms of KMD-3213 for the oral solid medicaments. The present inventors have found a novel crystal form suitable for oral solid medicaments. Based on the founding, the present invention has been accomplished.

It is required that a medicament for treatment always shows a constant action and effect. For that purpose, the content of an active ingredient must be substantially the same in a medicament. In such a case, the amount of crystal solvent or residual solvent such as adhesion solvent is important as well as the stability of the active ingredient. Concerning an oral solid medicament, solubility and specific volume of the active ingredient are also important factors.

Generally, an amorphous compound is often unsuitable for using for oral solid medicaments even though it shows better solubility, because its stability is bad, its specific volume is variable and it is easy to adhere solvent or to absorb moisture. On the other hand, a crystalline compound has lower solubility, but is stable and is less subject to incompatible combination with excipients or to change by time. In addition, since it is not hygroscopic and its specific volume is likely constant, it is easy to control the amounts of the active ingredient. Therefore, a crystal active ingredient is preferable for an oral solid medicament so long as the crystal has no problem about its solubility.

Besides, some compounds may have plural crystal forms, that is, polymorphism. Each crystal form may show different solubility or stability, and the differences may affect the hygroscopicity or pharmacodynamics. Therefore, in case that polymorphism exists in an active ingredient used for medicaments, confirmation of characteristics of its polymorphism used for medicament is required.

The present inventors had earnestly investigated polymorphism of KMD-3213 which is the most useful for dysuria treatment among the indoline compounds described in the above Literature 1. As a result, the inventors have found that there are at least three crystal forms and one of them is preferable to use for an oral solid medicament.

That is, KMD-3213 has at least three crystal forms shown by the powder X-ray diffraction patterns in FIG. 1 to FIG. 3. Concretely, the present inventors have found that there are three crystal forms, (1) a crystal characterized by main peaks of 5.5°±0.2°, 6.1°±0.2°, 9.8°±0.2°, 11.1°±0.2°, 12.2°±0.2°, 16.4°±0.2°, 19.7°±0.2° and 20.0°±0.2° as 2θ (hereinafter referred to as crystal form α); (2) a crystal characterized by main peaks of 7.0°±0.2°, 12.5°±0.2°, 18.5°±0.2°, 19.5°±0.2°, 20.7°±0.2° and 21.1°±0.2° as 2θ (hereinafter referred to as crystal form β); and (3) a crystal characterized by main peaks of 6.0°±0.2°, 10.6°±0.2°, 12.6°±0.2°, 17.1°±0.2°, 17.9°±0.2°, 20.7°±0.2° and 23.7°±0.2° as 2θ (hereinafter referred to as crystal form γ). These crystal forms can be prepared as follows.

The crystal form α can be prepared by dissolving crude crystals thereof in an appropriate amount of ethyl acetate, ethyl formate, acetone, methyl ethyl ketone, acetonitrile, tetrahydro-furan or a mixed solvent of acetone and acetonitrile (1:1) and so on, preferably ethyl acetate under heating, allowing to stand at room temperature, and making crystal precipitates gradually.

The crystal form β can be prepared by dissolving crude crystals thereof in an appropriate amount of methanol under heating, adding petroleum as a poor solvent, stirring the mixture vigorously, and making crystal precipitates forcibly and suddenly. The crystal form β can be also prepared by dissolving crude crystal thereof in ethanol or 1-propanol, and cooling quickly.

The crystal form γ can be prepared by dissolving crude crystal thereof in an appropriate amount of toluene, a mixed solvent of acetonitrile and toluene (1:4) or a mixed solvent of ethyl acetate and toluene (1:19), preferably toluene under heating, allowing to stand at room temperature, and making crystal precipitates gradually. The crystal form γ can be also prepared by dissolving crude crystal thereof in 2-propanol, and adding an appropriate amount of toluene thereto to precipitate a crystal.

Stability and hygroscopicity of each crystal form prepared as the above were measured. As a result, it is confirmed that the hygroscopicities of these three crystal forms are better than that of an amorphous form obtained by dissolving the crystals in dioxane and freezing and drying the solution and that there are little difference among them. Furthermore, it is also confirmed that the stabilities of these three crystal forms do not make much difference, and however that the crystal form α is white with almost no coloration in the appearance and the most stable. Accordingly, the present inventors found that the crystal form α is the best for the crystal for an oral solid medicament as regards stability and hygroscopicity.

Furthermore, among the crystal forms of the above KMD-3213, the crystal form β has a manufacturing issue in industrial preparation, since it is prepared by adding a poor solvent into a warmed solution to make crystal precipitates forcibly and suddenly as described above. For example, apparatuses for the industrial preparation become big and it may be difficult to get constant quality of the crystal. In case that the crystal form β is prepared by dissolving in ethanol or 1-propanol, and cooling quickly, it has another issue that the yields and purity tend to be irregular because different crystal forms are easy to mix therewith depending on the cooling speed, the temperature, the degree of stirring and the like.

The crystal form γ is prepared by cooling the warmed solution, allowing the crystal to precipitate gradually and unforcibly according to the usual recrystallization method, so the industrial apparatus can be small and it is easy to prepare a uniform crystal by controlling quantity of solvent, heating temperature, cooling temperature, cooling speed and the like. Therefore, there is no issue in the industrial preparation. However, the recrystallization solvent of this crystal form γ is toluene or a mixed solvent comprised mainly of toluene. Accordingly, the crystal form γ has a problem that it takes a lot of trouble to remove the solvent and it is comparatively difficult to completely remove the residual solvent because of toluene's high boiling point. As for a residual solvent in a row material for a medicament, an upper limit of quantity has been determined depending on the kind of solvent. The amount of toluene is required to be not more than 890 ppm. For that reason, the crystal form γ has a problem at this point.

On the other hand, the crystal form a has no problem in respect of industrial preparation as the crystal form β and can be prepared regularly, easily and in a large scale, in addition, without a problem of the residual solvent like crystal form γ. For that reason, the crystal form α is the most preferable for the oral solid medicament at points of industrial preparation and quality.

Accordingly, stable oral solid medicaments with high quality for dysuria treatment which contains an active ingredient in constant content can be prepared at low price by using KMD-3213 of the crystal form a as an active ingredient.

As described above, hygroscopicities and stabilities of the crystal forms β and γ of KMD-3213 are the almost same as those of the crystal form α. The crystal form β, the crystal form γ or their mixture can be used together therewith for the oral solid medicament of the present invention as active ingredients, if its quality including the residual solvent is in an acceptable range. In such a case, it is not a problem that the oral solid medicament for dysuria treatment of the present invention contains the other crystal forms other than the crystal form a as active ingredients, and a mixture of the crystal form a and the other crystal forms can be used as an active ingredient of the oral solid medicament of the present invention.

The oral solid medicaments of the present invention can be prepared by the conventional pharmaceutical procedure. For example, capsules can be prepared by admixing the crystal form a of KMD-3213 or a mixture of the crystal form α and the other crystal forms, and excipients such as D-mannitol or lactose into water, kneading the mixture, sieving and drying to produce granules, and admixing the granules with lubricants such as magnesium stearate, and filling an appropriate capsule with the resulting mixture.

Tablets can be prepared by producing granules according to a similar manner to that of the above capsules, admixing lubricants such as magnesium stearate into the granules, punching the mixture into tablets by the conventional procedure and coating with an appropriate coating material.

Since KMD-3213 represented by the above formula (I) in the present invention is unstable for light relatively, the content of active ingredient decreases depending on preserved condition with the passage of time. Therefore, concerning capsules or tablets, capsules filled using a light shielding capsule or tablets coated by a coating material with a light shielding effect is preferable. As examples of the light shielding capsule or the coating material with a light shielding effect, a capsule containing titanium oxide or a coating material containing titanium oxide is the most preferable.

Up to the present, as for the indoline compound represented by the above formula (I) or its pharmaceutically acceptable salt, or pharmaceutically acceptable solvate thereof, and pharmaceutical compositions comprising as an active ingredient the same, these general dosage forms have been exemplified and these compositions are only described as producible according to general or known methods, for example, in the above Literature 1 or 2.

As described above, crystal polymorphism of KMD-3213 represented by the above formula (I), which is comprised as an active ingredient in the oral solid medicament of the present invention, has not investigated at all, and therefore, there are no description concerning what types of crystal forms exist, how to prepare them and what property they have. Furthermore, oral solid medicaments comprising as an active ingredient each crystal form of the indoline compound represented by the above formula (I) of the present invention are not reported nor suggested at all.

KMD-3213 represented by the above formula (I), which is comprised as an active ingredient in the oral solid medicament of the present invention, is a known compound and, for example, can be prepared by the procedure described in the above Literature 1.

KMD-3213 represented by the above formula (I) in the present invention exerts an α₁-AR blocking effect with less effect on blood pressure and is extremely useful as a therapeutic agent for dysuria caused by prostate hypertrophy etc. It is also expected that KMD-3213 represented by the above formula (I) in the present invention can be used as agents for dysuria associated with urethra organized obstruction except for prostate hypertrophy, such as urethra stricture, urethra calculus and prostate cancer, dysuria associated with disorder of urination control nerves and dysruria associated with urethra functional obstruction, which is not included in any dysuria as referred above, such as bladder cervix sclerosis, chronic prostatitis and unstable bladder etc.

Dysuria associated with disorder of urination control nerves means dysuria caused by disorder of control nerves in the urethra or the bladder, for example, encephalopathy such as disorder of cerebral blood vessel and brain tumor, disorder of spinal cord such as injury of spinal cord and disorder of peripheral nerves such as diabetes and lumbar region spine stenosis. These disorders may occur in both men and women and are generally called as neurogenic bladder.

Dysruria associated with urethra functional obstruction not accompanying urethra organized disorder and disorder of urination control nerves means dysuria caused by urination difficulty, bladder cervix blockage, urethra syndrome, detrusor muscle-sphincter muscle cooperation insufficiency, chronic cystitis, prostatodynia, Hinman syndrome, Fowler syndrome, psychogenic dysuria, drug-induced dysuria, aging and the like besides bladder cervix sclerosis, chronic prostatitis and unstable bladder. These disorders are generally called as lower urinary tract disorders.

Since the medicaments of the present invention have high precision of content of an active ingredient and good elution properties, they can exhibit the action of KMD-3213 represented by the above formula (I) in the present invention effectively. Accordingly, the medicaments of the present invention are extremely useful as agents for the treatment of dysuria associated with urethra organized obstruction such as prostate hypertrophy, urethra stricture, urethra calculus and prostate cancer; dysuria caused by disorder of urination control nerves, namely neurogenic bladder; and dysuria caused by urethra functional obstruction, namely lower urinary tract disorders.

In the case of using the above medicament of the present invention for a practical medical treatment, the dosage of the active ingredient is appropriately determined depending on the sex, age or body weight of the individual patient, the condition to be treated and the like, which is approximately within the range of from 1 to 50 mg, preferably 4 to 20 mg per day per adult human.

The medicaments of the present invention may comprise as a further active ingredient at least one member selected from a group of an α₁-AR blocker except for KMD-3213, an anticholinergic agent, an antiinflammatory agent and an antibacterial agent.

The medicaments of the present invention may be also used in combination with a medicament comprising as an active ingredient at least one member selected from a group of an α₁-AR blocking agent except for KMD-3213, an anticholinergic agent, a 5α-reductase inhibitor, a sex hormone agent, an antianxiety agent, a cholinergic agent, a cholinesterase inhibitor, an antiinflammatory agent and an antibacterial agent.
